practical training at UNSW

background

In order to finish studies at the Computer Science department of Leipzig University, students have to do a practical training which has to be accepted by the department. Research project may count as well, so on my inquiries about contacts abroad, Professor Brewka contacted Norman Foo of the Knowledge Systems Group at the School of Computer Science and Engineering, UNSW, Sydney whom he had visited some time before. Professor Foo accepted to supervise a project I was to be working on.
In preparation of the stay in Sydney, I worked with Dr. Richard Booth. During this work, the general topic of a possible project emerged.

abstract

In this paper, we develop a logic that handles disbelief as an equal nested connective. Motivated by the desire to model contraction in a particular belief revision framework, we state desirable properties of the logic and show soundness and completeness of a proof theory based on them. We also illustrate how an essential part of the belief revision framework can be interpreted in an argumentation framework.
